There are many reasons why an individual may have limited or no use of one hand. The main causes are: diabetes, vascular disease, trauma (e.g. an industrial accident), congenital conditions affecting the musculo-skeletal or nervous system and infections (such as sepsis and osteomyelitis). It is estimated that there are at least 35,000 persons with amputations within Australia, which is likely to be an underestimate given that it is based on data gathered by the Australian Bureau of Statistics in 1993. Statistics from the US show that the most common amputation is partial hand (one or more fingers) and the next most common is loss of an arm.
